SKATE.

Application Jcd Septemberil', 1922. Serial No. 588,439.

.To all whom #may concern.

Be it known that WALTER DAvERKosEN and PAUL H. DAvEnnosnN, citizens of the United States, `residing at Janesville, in the county of Rock and State of Wisconsin, have invented new and useful Improvements in Skates, of which the following is a s ecifcation.

his invention relates to im rovements in skates and has for its princlpal object to produce an ice skate having vballbearing rollers which have their contacting surface movement of the skate.

Another object of the invention is to produce an ice ball bearing roller skate having rollers which are provided with a cone core which is designed to holdthe ball bearings therein.`

A further .object of the invention is to produce ball bearing rollers which may be used or applied to any standard ball bearing roller skate and used in the capacity of an ice skate, said rollers being-simple in construction, eiiicient in operation and manufactured and marketed at a moderate cost.

This invention also consistsin certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail reference vwill be had to the accompanying drawings wherein like characters of reference denote like or corres onding parts in the several views, andin w ich Inv the drawin s: p r l Figure 1 is a side elevation of the invention as applied to a skate.

Figure 2 is a radial sectional view of one of the rollers partly in side elevation.'

Figure 3 'is a view showin the rollers having grooves of different `c aracter and being arranged in formation for association with the skate.

Referring now to the drawings wherein like characters of reference denote corregpondin arts 1 indicates a frame of a ate o t e ordinary construction which hasadxelpending bearing brackets 2 en ging an e 3 which is journalled in ro ers 4` for connecting said rollers tothe skata` Each rollers has its contacting surface grooved or cut differently so that the rollers will obtain a rm griponthe ice and therebly eliminating lateral movement of the te. The rollers consists of spaced spokes 5 and have a cone corev 6 forming the center thereof.

Exteriorly threaded vmembers 7 are deagainst the Vmembers 7 for holding them within the core of the ro1ler,so as to eliminate any danger of losing,l the ball bearings contained within said core. The axles which are journalled in the rollers are designed to connect the rollers in pairs and have their outer ends (provided with nuts 10 which bear against sai gaskets 'for positioning the latter and holdin the members 7 within the core of the ro ler, and thereby preventing the ballbearings from beinglost. f

From the above itI will be seen that each of these ice ball bearing rollers have their contacting4 surface grooved 'or' cut diferently, so as to prevent the lateral movement of the skate. Itis also apparent that these rollers may be used on any standard roller skate and used in the capacity of an ice skate.

It is thought from the foregoing description that the advantages and novel features i of Indy invention will be readily apparent. vI esire it to be understood that I may make changes in the construction and inv i the combination and arrangement of the PAUL H. DAVERKOSEN. WALTER DAVERKOSEN.
